Moving the Goalposts

One recipe today - basically a relish made from storecupboard/fridge ingredients, and one that eats well with 'burgers. Make as you wish to use as it will not store for any length of time - at most a couple of days in the fridge.
Beetroot Relish:
7 oz (200g) cooked beetroot, cut into small cubes
2 large or 3 small pickled onions, finely chopped
2 tblsp green olives, pitted and roughly chopped
1 tblsp chopped fresh mint
salt and pepper
Mix everything together with seasoning to taste, and serve in a small bowl.
